That does not justify a bogus warning.

Show me a single case where

(setq a ...)
(setq a ...)

wouldn't be better be written some other way (with "better" meaning a
completely subjective measure).

Yet we don't warn about it.  We don't press matters of style lightly.

Or more serious, a single case where
(sort xxx ...) or (nconc xxx ...) outside of a (setq xxx ...) wouldn't
better be written some other way.

We don't warn about those either.
